The structural map

Your post, placed among the posts the study measured.

AI posts, five modelsHuman postsYour post
In the figure, this post sits on the side where the study's human posts are. The SlopShape study measured 13,500 posts, 2,250 written by people and 11,250 by five AI models. The map places 12,900 of them.
How this figure is made

The map is fitted on the five dimensions the Slop Checker asks, 109 of the study's questions, not the eleven dimensions the paper fits. It is the same family as the paper's figure rather than the identical one. The clouds show a fixed sample of the study's posts, 900 for each of the six classes the paper publishes, which is 900 human posts and 4,500 AI ones; the fit uses every post.
